The corrugated hose on my Oxycheq wing recently separated from the low pressure inflator during a dive. It only had a single tie-wrap holding it in place, and that apparently loosed enough to allow the failure. I reattached it using two tie-wraps, which I consider the minimum. But, it made me curious. DR and Halcyon appear to use screw clamps (at least that is all I have seen on them) for the connection. Does anyone have experiences suggesting that a screw clamp is substantively better than using a couple of tie-wraps (I can think of some theoretical reasons, I guess)? Also, in looking at the inflator valve before reattaching it, it appeared to have a non-sticky coating of some kind on the end, either a (now dried) adhesive or perhaps something like the scuba equivalent of plumbing joint compound. For those of you who work on BCs (professionally or personally) do you put anything on the male end of the inflator before attaching the corrugated hose?
